Description of key information

Toxicity to microorganisms (Pseudomonas putida): 17-hr EC50 = 4812 mg/L and 17-hr EC10 = 3373 mg/L

Key value for chemical safety assessment

EC50 for microorganisms:
4 812 mg/L
EC10 or NOEC for microorganisms:
3 373 mg/L

Additional information

In a DIN 38412, part 8 (Pseudomonas Zellvermehrungshemm-Test), the 17 -hr EC50 for n-Vinylpyrrolidone (nVP) for microorganisms (Pseudomonas putida) was determined to be 4812 mg/L and the 17 -hr EC10 was determined to be 3373 mg/L (BASF, 1988). Given these results, it can be said that nVP exhibits little to no toxicity to microorganisms.
